Among them, the waste oil water tank 1 is installed in the engine room. The waste oil water tank 1 is connected to an oil waste inlet pipe 6, and the oil waste inlet pipe 6 is connected to the waste oil hand pump 2. One side of the lower part of the waste oil water tank 1 is connected to the waste oil water shore connection 4; a branch tee is connected to the inlet of the waste oil hand pump 2, and corresponding control valves are provided at each inlet of the branch tee. One of the inlets of the branch tee is connected to the engine room waste oil water floor drain 3 through the waste oil water extraction branch pipe 5, and the other inlet of the branch tee is connected to an inlet connection pipe 9, and the inlet connection pipe 9 is connected to the deck waste oil water floor drain 10. A direct drain pipe 11 is provided between the inlet connection pipe 9 and the waste oil water tank 1, and a deck stop valve 12 is provided on the direct drain pipe 11. Check valves 8 are provided on both the inlet connection pipe 9 and the waste oil water extraction branch pipe 5, and a valve 21 is provided on both the inlet connection pipe 9 and the oil waste inlet pipe 6. The valve 21 is an ordinary control valve for closing the corresponding pipeline.

[0019] The waste oil water tank 1 includes a box body 20, and a box cover 13 is buckled on the top of the box body 20. An initial filter partition 14 is vertically fixed at one end of the inner cavity of the box body 20. A sedimentation channel is reserved between the bottom of the initial filter partition 14 and the bottom of the box body 20. An initial filter screen 15 is provided in the box body 20 on one side of the initial filter partition 14. An oil waste partition 16 is vertically fixed at the other end of the inner cavity of the box body 20. A sedimentation baffle 17 is vertically fixed at the bottom of the box body 20 between the oil waste partition 16 and the initial filter partition 14. The horizontal plane at the top of the sedimentation baffle 17 is lower than the horizontal plane at the bottom of the initial filter partition 14, and the horizontal plane at the bottom of the oil waste partition 16 is lower than the horizontal plane at the top of the sedimentation baffle 17. A drainage channel is reserved between the bottom of the oil waste partition 16 and the bottom of the box body 20 away from the initial filter screen 15. A clear water area is formed between the oil waste partition 16 and the end of the box body 20. A drain pipe 18 is provided on the box body 20 in the clear water area, and a water retaining baffle 19 is vertically fixed in the box body 20 at the drain pipe 18. The horizontal plane at the top of the water retaining baffle 19 is lower than the horizontal plane at the bottom of the initial filter screen 15; the water retaining baffle 19 is U-shaped when viewed from above, and the bottom and both sides of the water retaining baffle 19 are hermetically connected to the inner cavity wall of the box body 20, and the drain pipe 18 is located between the two side walls of the water retaining baffle 19. The waste oil water shore connection 4 is connected to the box body 20 below the initial filter screen 15. Filter water holes penetrating both sides are provided on the initial filter partition 14 above the initial filter screen 15, and oil filter meshes are provided in the filter water holes. The outlet of the oil waste inlet pipe 6 is located above the initial filter screen 15.

[0020] After adopting the above solution, the oily sewage mixture on the ship's deck is collected through the deck oily sewage floor drain, and then enters the oily sewage tank through the inlet connecting pipe and the oily sewage inlet pipe. The oily sewage mixture in the engine room is collected through the engine room oily sewage floor drain and enters the oily sewage tank through the oily sewage extraction branch pipe and the oily sewage inlet pipe. Among them, the inlet connecting pipe can also directly enter the oily sewage tank through the direct discharge pipe (the outlet of the direct discharge pipe passes through the tank cover and is located above the primary filter screen); when the floor drain or pipeline is blocked, the suction can be increased through the manual oily sewage pump; a sewage area is formed between the settling baffle below the primary filter screen and the box body, and the oily sewage shore connection is connected in the sewage area;

[0021] There are three ways for the oily sewage mixture of the engine room oily sewage floor drain 3 and the deck oily sewage floor drain 10 to be discharged into the oily sewage tank:

[0022] First, close the deck stop valve 12, open the control valves at all inlets on the branch tee. The oily sewage from the engine room oily sewage floor drain 3 passes through the oily sewage extraction branch pipe 5, and the oily sewage from the deck oily sewage floor drain 10 converges at the branch tee through the inlet connecting pipe 9, and then enters the oily sewage tank together by the manual oily sewage pump 2. This method is used for normal drainage operations.

[0023] Second, open the deck stop valve 12, close the inlet valve of the branch tee and the inlet connecting pipe 9, and open the other two inlet valves of the branch tee. At this time, the oily sewage from the engine room oily sewage floor drain 3 enters the oily sewage tank through the oily sewage extraction branch pipe 5 and the branch tee by the manual oily sewage pump 2; the oily sewage from the deck oily sewage floor drain 10 is directly discharged into the oily sewage tank from the direct discharge pipe 11 through the inlet connecting pipe 9; this method is used when there is more deck water accumulation (rainy weather) to prevent the oily sewage inlet pipe 6 from not being drained completely.

[0024] Third, open the deck stop valve 12, close the inlet valve of the branch tee and the manual oily sewage pump 2, open the other two inlet valves of the branch tee to make the manual oily sewage pump 2 not intake water. The oily sewage from the deck oily sewage floor drain 10 passes through the inlet connecting pipe 9, and the oily sewage from the engine room oily sewage floor drain 3 passes through the oily sewage extraction branch pipe 5, and then enters the inlet connecting pipe 9 through the two inlets of the branch tee and is directly discharged into the oily sewage tank from the direct discharge pipe 11; this method is used for repairing or replacing the manual oily sewage pump 2.

[0025] After adopting the above solution in this embodiment:

[0026] The partition situation in the box body: A settling channel is reserved between the bottom of the primary filter partition 14 and the bottom of the box body 20;

[0027] A drainage channel is reserved between the bottom of the oily sewage partition 16 and the bottom of the box body 20, and the drainage channel is used for the discharge of clear water;

[0028] A sewage area is formed between the settling baffle below the primary filter screen and the box body, and the sewage area is used for the precipitation of sediments in the sewage.

[0029] A clear water area is formed between the oil pollution partition plate 16 and the end of the box body 20 far from the primary filter screen 15, and the clear water area is used to store and overflow clear water;

[0030] A secondary sedimentation area is formed between the sedimentation baffle 17 and the end of the box body 20 far from the primary filter screen 15;

[0031] Working principle:

[0032] First, water is injected into the secondary sedimentation area according to actual needs, and the height of the injected water is the height of the sedimentation baffle. At this time, the bottom of the oil pollution partition plate 16 is located between the water surfaces of the secondary sedimentation area, forming a water seal, and the floating oil will not enter the drainage channel; therefore, the bottom horizontal plane of the oil pollution partition plate 16 must be lower than the top horizontal plane of the sedimentation baffle 17, otherwise the water seal cannot be formed;

[0033] When water is not injected first, the water and oil pollution in the sewage area will first flow to the secondary sedimentation area, and there will be a small amount of floating oil on both sides of the oil pollution partition plate 16 (including the clear water area). When the water seal is formed (the height of the injected water is the height of the sedimentation baffle), the floating oil in the direction of the primary filter screen will be blocked by the oil pollution partition plate 16, and the small amount of floating oil in the clear water area will be discharged with the water;

[0034] The oily sewage mixture in the oil pollution inlet pipe 6 (direct discharge pipe 11) falls onto the primary filter screen after entering the box body, and impurities are filtered through the primary filter screen. The oily sewage mixture after impurity filtration falls into the sewage area (between the sedimentation baffle below the primary filter screen and the box body); when the incoming oily sewage mixture is relatively large, the water will be discharged from the water filtering holes, and the impurities will also be blocked inside the primary filter screen;

[0035] The sedimentation channel is used to enhance the oil-water separation effect when the oily sewage is falling (the density of oil is smaller than that of water, and it will fall slightly slower), so that the oily sewage can be separated more quickly after falling;

[0036] After the oily sewage mixture falls into the sewage area, during the process of the water level rising, the sediment (silt) in the oily sewage mixture will undergo primary sedimentation in the sewage area, and the oil will float to form floating oil (at this time it is oily sewage);

[0037] When the height of the oily sewage exceeds the height of the sedimentation baffle 17, it overflows from the top of the sedimentation baffle 17, and the floating oil also rises (the silt will no longer overflow with it). Under the action of the water seal, the floating oil is blocked between the oil pollution partition plate 16 below the primary filter screen 15 and the end of the box body 20;

[0038] The sewage then enters the secondary sedimentation area under the push of the subsequent incoming water for secondary sedimentation, and the water level in the clear water area rises synchronously under the push of the incoming water. In this way, the water in the clear water area is the water after secondary sedimentation and does not contain floating oil;

[0039] Under the continuous action of water inlet and sedimentation, the water level in the clear water area continues to rise. When the water level reaches the top of the water baffle, it overflows from the top of the water baffle, and an overflow area is formed between the water baffle and the end of the box body. When the water level in the overflow area is higher than the drain pipe, the clear water is discharged from the drain pipe (under the thrust of the newly incoming sewage, the clear water continuously overflows over the water baffle and is discharged from the drain pipe);

[0040] In this way, a continuous treatment effect of physical decontamination, sedimentation, oil separation and drainage is formed in the whole box body; after the ship docks, open the box cover to remove the floating oil first, and then connect the sewage and oil through-shore joint to pump out the sewage in the sewage area (the water below the sedimentation baffle in the clear water area will not be pumped out during pumping). The structure after adopting this scheme is reasonable and has good use effect.

[0041] When the water level in the oil and sewage water tank reaches the height of the water baffle 19, the clear water will overflow from the top of the water baffle and finally overflow from the drain pipe to the outside of the ship. Only oil stains, sediment and impurities will be left in the oil and sewage water tank, and finally they can be pumped out through the shore connection joint.

[0042] The above-described embodiments are only the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Therefore, all changes made according to the shape and principle of the present invention should be covered within the protection scope of the present invention.
